this is bbc news — the headlines at 10:00pm. the bbc understands the man being questioned over the death of mp sir david amess, had been referred a few years ago to the government's prevent scheme — he's been named by whitehall sources as 25—year—old ali harbi ali. tonight in leigh—on—sea, residents gathered for a candlelit vigil, in memory of their mp. side by side in grief — the prime minister and leader of the opposition visit the scene where of yesterday's murder.

good evening and welcome to bbc news. police have tonight been given more time to question a man arrested in connection with the murder of the mp sir david amess. the 25 year old suspect has been named by whitehall officials as ali harbi ali. the bbc understands he was referred a few years ago to the government's prevent scheme, which tries to stop people being drawn into extremism. sir david was stabbed during a constituency surgery in a church hall in leigh—on—sea yesterday lunchtime. daniel sandford reports. a united front in the face of a suspected terrorist attack. the prime minister, the leader of the opposition, the speaker of the house of commons and the home secretary. four of the most senior politicians in the land at the church today where sir david amess mp was murdered. he was killed doing a job that he loved, serving his own constituents as an elected democratic member.

and, of course, acts of this are absolutely wrong and we cannot let that get in the way of our functioning democracy. it was formally declared a terrorist incident late last night, with forensic specialists poring over the crime scene, counter terrorism detectives are leading the investigation. the early enquiries suggesting the motive was islamist extremism. through friends, eyewitnesses have suggested that the attacker waited in the queue at sir david's constituency surgery yesterday, before stabbing the mp several times with a knife and then waiting for police to arrive. sir david was known and loved for his hands—on approach with voters and those who have campaigned with him had warned him of the risks. i used to go out on the doorsteps on the cold, dark nights in the rain and i used to be a bodyguard, many years ago. i said, "david, you should have somebody with you on these things, it's not safe".

southend has two representatives in parliament and the other mp, james duddridge, paid this emotional tribute to his friend. the community hasjust been hit sideways by this. it's notjust a member of parliament, notjust the local member of parliament but he really did touch people's lives in a way that most mps don't manage to do. at southend civic centre this afternoon, a simple ceremony to remember an mp that not everyone agreed with but who everyone respected and loved. # amazing grace... #. daniel sandford, bbc news, leigh—on—sea. earlier, i spoke to the former labour mpjohn woodcock — now lord walney — an independent adviser on political violence. he's been conducting an independent review of political violence and disruption, due to be submitted by the end of year.

two main areas spring to mind and it springs back to the time from when joe cox died. and with sir david losing his life. and i think on policing and security, harriet harman had a really strong point where there is surely a media know and i think it's realistically talking about the kind of closed protection for members of parliament that the home secretary and prime minister has but in those days and weeks afterjoe died we certainly did review our security and increased it in our offices in general but many mps wanted to keep the open surgeries in an open environment there was one of those.

and i think that while there was an increased level of communication with the police as to where we were having surgeries there has not been, to my knowledge, a discrete police presence that most of those events and i realise that is an issue that will increase levels of resource for the police but surely it is something that ought to be on the table now and could be done in a discrete way where conversations between constituents and mps are still remaining in private but there is, just as there will be a routine police presence at a whole range of things across any constituency in a given week, we are talking about, you know, an hour a week, may be less, may be a bit more for know, you're not talking about round—the—clock police presence for

mps which would not be realistic. you are not talking about having a police officer looming over the constituent as they talk about their private matters, you're talking about more of a visible presence, may be somebody at the door, someone across the road, something that reminds people that this is being watched and it is not an isolated event. ., ., , event. so, for example, in the weeks afterjoe event. so, for example, in the weeks afterjoe cox — event. so, for example, in the weeks afterjoe cox died _ event. so, for example, in the weeks afterjoe cox died and _ event. so, for example, in the weeks afterjoe cox died and i _ event. so, for example, in the weeks afterjoe cox died and i was _ event. so, for example, in the weeks afterjoe cox died and i was still- afterjoe cox died and i was still an mp then and we worked with an increased level of information. the police wanted surgery was happening and they would check it out and may be at the local supermarket and they would pop there the beginning and from there at the end. there is surely something that can be done in an increased way in that regard that can give a. the terror attacks over

recent years have shown that if people are determined to commit a level of violence against individuals including of course against a police officer with pc palmer outside the parliament gates, they can be no guarantees, but that might be a level of stepping up which is not happening at present, which is not happening at present, which may give an increased level of reassurance but there were two main things that came to mind and if you don't mind, i think the second big area is, afterjoe died herfriends and colleagues in parliament really pushed on one of her big ideas which was we have more in common as parliamentarians and politicians and political activists from across different parties, we all in general want to do the best for people. we have different ways of doing it and we should look on our people and

other parties as opponents but not as enemies to be hated or denigrated or dehumanised in some respects and i was reflecting on the fifth anniversary of her death recently that we felt a long way away from that we felt a long way away from that in lots of the ways that people spoke. i mean, yes, there was a real problem of course in social media and many of my colleagues, particularly female colleagues experience that but there is a greater need for leadership across those of us in position of responsibility is to think about how we talk about each other. this responsibility is to think about how we talk about each other.— we talk about each other. this is a difficult area _ we talk about each other. this is a difficult area because _ we talk about each other. this is a difficult area because people - difficult area because people express themselves in different ways and with different degrees of passion but i am reminded of the situation only three or so weeks ago when angela rayner was rebuked by her colleagues stood her ground and the use of the word some to describe conservatives. is that the sort of thing, no you're looking 7 but not

looking to point the finger at individuals, is that what makes you uncomfortable and you don't think it causes anything but kind of poison the atmosphere and dehumanises the people who do politics7 the atmosphere and dehumanises the people who do politics?— people who do politics? look, i don't think _ people who do politics? look, i don't think this _ people who do politics? look, i don't think this is _ people who do politics? look, i don't think this is a _ people who do politics? look, i don't think this is a weekend i people who do politics? look, i i don't think this is a weekend for, you know, particular links to be made and there are many that are not going to want to be the ones to cast the first stone in this and many others who are spoken, times i've spoken about my opponents both outside of the labour party and inside in a way that was probably unwise but i really hope this is the moment. we thought this would have happened after she died and to an extent it did and did achieve some great things but there were still

demonstrably a problem over there in recent weeks and months in one of the interviews was an example of that and we have to look again at this now because there are different factors that can drive people towards political violence but what people often have in common despite different ideological viewpoints as they have a sense of righteousness in their cause that they think it is overwhelmingly the right thing to do and often it legitimises, in their mind, behaviourand and often it legitimises, in their mind, behaviour and acts of supreme tragic violence. a range of unacceptable behaviour of below that which they think the righteousness of their cause enables and that is something looking at as part of my

review and we do need to be much more vigorously challenging then perhaps we have done in recent years. perhaps we have done in recent ears. . , , , years. that review will be presented before christmas, _ years. that review will be presented before christmas, you _ years. that review will be presented before christmas, you have? - years. that review will be presented before christmas, you have? that . years. that review will be presented before christmas, you have? that is the lan before christmas, you have? that is the plan and — before christmas, you have? that is the plan and we _ before christmas, you have? that is the plan and we wait _ before christmas, you have? that is the plan and we wait to _ before christmas, you have? that is the plan and we wait to see - before christmas, you have? that is the plan and we wait to see what. the plan and we wait to see what happens after that but my planners tried to get it into the prime minister and home secretary before christmas. the minister and home secretary before christmas. ., ., ~ ,, christmas. the death of david amiss and the death _ christmas. the death of david amiss and the death of— christmas. the death of david amiss and the death of joe _ christmas. the death of david amiss and the death of joe cox, _ christmas. the death of david amiss and the death of joe cox, the - christmas. the death of david amiss and the death of joe cox, the very i and the death ofjoe cox, the very serious injury experienced and other deaths and serious injuries, these are at one end, the very extreme end of the kind of targeting people who are in politics whether they be local councillors, mayors, police and crime commissioners and peas, meps whatever. are you worried about the kind of not so much the language but a level of intimidation towards people do politics that might

protest are intimidating from speaking, intimidating from getting involved which is damaging and can really damage as as a liberal democracy and we have to think understand that as a spectrum just as with violence against women and girls, sexual violence where people are rightly spoken about spectrum of behaviour and red flags and things that ought to have been tackled further down the track and i think we need to reconsider that within the framework of political discourse and how we relate to each other.

the man arrested for killing mp sir david amess is named as ali harbi ali, a british man of somali heritage. the 25—year—old was arrested at the scene of the knife attack. detectives are treating it as a terrorist incident, which may be linked to islamist extremism. ali harbi ali is understood to have had been referred to the government s prevent scheme a few years ago, the programme intended to stop people being drawn into extremism. earlier, the prime minister and leader of the opposition paid their respects where the attack took place. sir david had been warned about his safety. a review has begun into how to protect mps. we live in an open society, a democracy. we cannot be cowed by any individual, or any motivation,

people with motives, to stop us from functioning. also tonight... morrisons say shortages of staff and stock are forcing them to delay opening new supermarkets. and on a mission to jupiter's asteroids — the spacecraft aiming to uncover the origins of the solar system. good evening. the man arrested by police following the killing of the essex mp sir david amess has been named tonight as ali harbi ali. the 25—year—old is british, of somali heritage. it's understood that he was referred to the government's prevent programme a few years ago, the scheme intended to stop people being drawn into terrorism. sir david was stabbed multiple times

during a constituency surgery in a church hall in leigh—on—sea. the prime minister, borisjohnson, and the leader of the opposition, sir keir starmer, today laid flowers together at the scene. our home affairs correspondent daniel sandford is in leigh—on—sea. yes, martine, the initial shock at the brutal attack yesterday has turned into a kind of deep sadness today, as details of the attack became clearer and the suspect was named. we've been watching all day as people have been bringing flowers, some of them weeping openly. the day began with a sombre visit by some of sir david's most senior fellow visit by some of sir david's most seniorfellow mps. a united front in the face of a suspected terrorist attack. the prime minister, the leader of the opposition, the speaker of the house of commons and the home secretary — four of the most senior politicians in the land at the church hall today where sir david amess mp was murdered. he was killed doing a job that he loved, serving his own constituents

as an elected democratic member. and, of course, acts of this are absolutely wrong and we cannot let that get in the way of our functioning democracy. it was formally declared a terrorist incident late last night — early enquiries suggesting the motive was islamist extremism. the man in custody, ali harbi ali, is understood to have been referred to the government's prevent scheme a few years ago. the scheme's designed to stop people being drawn into terrorism. he was never a formal subject of interest for the security service mi5. through friends, eyewitnesses have suggested the attacker waited in the queue at sir david's constituency surgery yesterday, before stabbing the mp several times with a knife in front of his assistant and then waiting for police to arrive. sir david was known and loved for his hands—on approach with voters and those who've campaigned with him had warned him of the risks. i used to go out on the doorsteps on the cold, dark nights in the rain

and i used to be a bodyguard, many years ago. i said, "david, you should have somebody with you on these "things, it's not safe". southend has two representatives in parliament and the other mp, james duddridge, paid this emotional tribute to his friend. i mean, the community hasjust been hit sideways by this. it's notjust a member of parliament, notjust the local member of parliament but, you know, he really did touch people's lives in a way that most mps don't manage to do. tonight at the local sports field, hundreds of people gathered to remember the mp so many of them knew personally. and he was a very, very decent human being. an mp that not everyone agreed with, but who everyone respected and loved. ali harbi ali has now been arrested on suspicion of terrorism, having originally been arrested on suspicion of murder. and that means

he can now be held until friday before he has to be charged or released. he has also been moved from essex to a police station in london, and three london police stations are now being searched. a lot of work has been done on his background which has thrown up his past involvement in the prevent programme, but at the moment, he is only being held on suspicion of terrorism, he has not been charged. martine. daniel sandford, thank you very much. police forces across the uk are contacting all mps to discuss their personal safety. meeting constituents is seen as central to their role as representatives. but the death of sir david amess has re—opened a debate about the risks they face. our political correspondent damian grammaticas reports. around the country today, mps continuing to hold their surgeries. robert largan in the peak district saying he'll "keep doing this all year round". craig williams in montgomeryshire thanking welsh police for being there to give reassurance, and kieran mullan in cheshire

saying, "we must not let people force us to do things differently." but today, there are changes. in south wales, a police guard for an mp's coffee morning and he already felt vulnerable. we now have cctv at the front and rear of the building. we had to have new security fitted onto the front and rear doors. we have panic alarms in the constituency office that staff often wear around their necks. we have installed panic alarms at my front door, at the side of my bed. you know, this has become too much of the new normal. mps' security was reviewed afterjo cox was murdered five years ago, shot and stabbed as she left a meeting in her local library by a white supremacist. in 2010, stephen timms mp survived an attack by a woman who'd watched radical islamic sermons online. she was bundled away. and in 2017, four passers—by and pc keith palmer were all killed outside parliament in what the police called

an act of islamist—related terror. the mp who was here that day and tried to save pc palmer's life has said that meeting constituents is vital but they should be paused. the home secretary's announced a review of mps' security and he says that should be completed first. i would recommend that no mp has a direct surgery until... you know, you can move to zoom. there's other ways... you can actually achieve an awful lot over the telephone, you can get things moving far faster than having to wait for the surgery date, as well. but for sir david amess, meeting constituents was a vital part of his job. so, the question now is, how much further should security be tightened 7 many believe things have to be reappraised but mps themselves must decide. it's not a question of carrying on with business as usual and just regarding this as an occupational hazard of being an mp. nor of having close security such as the home secretary has, or the prime minister or the foreign secretary needs to have. we need to have a discussion

about how we strike the balance. it's a balance that will be are hard to find. two years ago in the royal albert hall, a concert for people with learning disabilities — sir david amess championed this cause, he loved his public role. mps are public figures, accessible and therefore vulnerable. damian grammaticas, bbc news. britain's fourth biggest supermarket, morrisons, has warned that labour shortages are delaying new store openings and products reaching shelves. its chief executive, david potts, told the times newspaper that more visas are needed forforeign workers. it follows measures announced by the government to reduce the pressure on supply chains. our business correspondent katy austin reports. the global supply chain is under huge strain as economies reawaken. 0nce imported products reach the uk, a shortage of lorry drivers means containers are often getting delayed at ports. when you have a shortage of labour in terms of hgv drivers, those domestic drivers, it means that the goods are sitting

around slightly longer at the ports waiting to be collected. there are labour shortages in other sectors, too, including construction, hospitality and food production. now, the boss of morrisons has said that while there are plenty of products on the shelves, underlying strain in the supply chain is affecting availability, while a lack of materials such as cement and bricks is delaying investment in new shops and refurbishments. he called for more visas forforeign workers. the government has already offered temporary visas for some meat workers. there are 5,000 visas available for drivers, too. other european countries also have shortages, but this driver in romania told the bbc rising wages in the uk were attractive. translation: a really good friend | of mine left for the uk last week. | he went for three months. everyone who went there tells me the wages are really good. i'm tempted, too.

but only 20 of those visas have so far been approved. in the latest effort to ease the pressure, particularly before christmas, ministers now plan to let overseas drivers do more deliveries when they're on uk soil. i don't think the change yesterday will make much difference. so, what do you think would make a difference, then7 we need to encourage young drivers into the industry. we need to make facilities better for drivers. the general public need to treat drivers better. the government says immigration isn't the long—term answer to filling britain's record number of vacancies. it wants to develop a high—skilled, high—wage economy. some businesses say they still need a better short—term fix. katy austin, bbc news. the government's latest coronavirus figures show that there were 43,423 new infections recorded in the latest 24—hour period. that means on average there were 41,359 cases per day in the past week. another 148 deaths have been

recorded, that's of people who died within 28 days of a positive test, which means that on average there were 119 deaths per day in the past week. on vaccinations, 85.9% of the population aged 12 and over have had their first dose, and 78.8% have been double—jabbed. nasa has successfully launched its first mission to study jupiter's trojan asteroids, two vast clusters of space rocks that surround the planet. scientists believe they are made up of matter that formed the solar system's outer planets. duncan kennedy reports. three, two, one, zero. the start of a 4 billion milejourney. lift off, atlas v takes flight. the atlas v rocket is carrying a craft called lucy, that aims to go into orbit around jupiter and study a group of asteroids called trojans, some of which are the size of a city.

so, what are the trojan asteroids7 they're asteroids that orbit withjupiter around the sun that ultimately hold the clues to the formation of our solar system... lucy's giant solar panels would only generate enough electricity to power a few light bulbs on earth, but around jupiter, it's enough to reach the trojan asteroids and ask questions like — what they made of and where do come from? by going to visit a large number, eight asteroids in total, over the mission lifetime, we'll really better understand all about the asteroids. so, if you only see one, maybe you got a bit of a funny one but by seeing eight, you get to really understand what's going on in this population. scientists want lucy to test their theory that the early solar system was juggled around by gravity, with some objects being thrown in and others out, just like billiard balls. but they'll need patience. lucy's expected to be operating around asteroids for the next 12 years. duncan kennedy, bbc news.

let's catch up with all the day's sport now with john watson at the bbc sport centre. good evening. thanks, martine. news on manchester united and liverpool in the premier league to come. if you're waiting for the scores on match of the day and sportscene, you might want to look away now. united lost ground on their rivals, beaten 4—2 by leicester. manchester city, chelsea, who top the table tonight, and liverpool all won, the latter beat watford 5—0. rangers were unable to extend their lead in the scottish premiership. a late goal from second—placed hearts means the gap stays atjust a point. celtic beat motherwell to climb up to fourth, dundee lifted themselves off the bottom, beating abderdeen. leicester tigers maintained their perfect start in rugby union's premiership. exeter chiefs, meanwhile, beat wasps, the victory coming after their opponents had told their travelling fans not to wear the native american headresses associated with the club's name,

as patrick gearey explains. exeter chiefs fans are among the most distinctive in british sport, but should the headdresses be taken off? before this game, wasps asked off7 before this game, wasps asked that the heads of chiefs fans be kept further free, fronting a debate about whether exeter�*s branding is offensive to native americans. on the pitch, exeter�*s image is one of perpetual motion. having slumped was to last time, henry slade put them in front. the lead was then stretched, then contracted, and finally pummelled out of existence, welshman thomas young going over for wasps. the second half would be hardfought wasps. the second half would be ha rdfought battles all over wasps. the second half would be hardfought battles all over the pitch, and somehow, off it, even the water carrier got in trouble. 13 minutes to go, wasps' lead was just a point. not enough to stand up to exeter�*s final push. jonny hill's

try won it, and for exeter, a match that began with a talking point ended with a bonus point. patrick gearey, bbc news. and oisin murphy has become champion jockey for a thrid time at flat racing's season finale at ascot. the queen was in attendance on champions day. the feature race, the champion stakes, was won by sealiway. adayar finished fifth and with it went william buick�*s hopes of pipping murphy to the jockey�*s title. and cameron norrie is leading grigor dimitrov in the semifinals at indian wells, coverage on 5 live sports extra now. that, though, is all from me. martine. that's it for now. there's continuing coverage on the bbc news channel of events following the killing of sir david amess. and the home secretary, priti patel, will be appearing on the andrew marr show tomorrow morning at 9am on bbc one.
